19.3 Startup
The size of the block buffer is adjusted via the machine data:
MD62571 $MC_RESU_RING_BUFFER_SIZE
Default setting:
MD62571 $MC_RESU_RING_BUFFER_SIZE = 1000
RESU portion of the total heap memory
The RESU portion of the total heap memory that can be used for compile cycles is set via the
machine data:
MD62572 $MC_RESU_SHARE_OF_CC_HEAP_MEM
Default setting:
MD62572 $MC_RESU_SHARE_OF_CC_HEAP_MEM = 100
